Abstract
Stress-strain behavior in compression of lightweight fiber reinforced concrete under monotonic and cyclic loads G. Campione, L. La Mendola Dipartimento di Ingegneria Strutturale e Geotecnica, Universita, Viale delle Scienze, Palermo, Italy Abstract Compressive experimental behavior of lightweight fiber reinforced concrete combined with traditional transverse steel reinforcement consisting in steel spirals was analyzed. Lightweight aggregates were utilized to give lightness to the composite, and steel hooked fibers were added to the matrices besides the traditional steel lateral reinforcement to increase the ductility of members in compression. The investigation was carried out through compressive tests on cylindrical specimens, by imposing monotonic or cyclic displacements and recording the full load-deformation curves. Empirical stress-strain equations were adopted to reproduce with a good level of approximation the actual behavior of cylindrical specimens under uniaxial co
